The handheld pressure gauges Type HMG1 and HMG6 easures difference- and absolute pressure, relative pressure in air and non aggressive gases. Both types has a 3,5-digit LC-display ith 12,7 mm figure height. The signal can drive a 0-1 V analog-output (type HMG1-1, HMG6-1). The pressure gauges reaches a high liability and precision. Power supply is a 9-V-battery type 6F22. The battery power control generates “low bat“ on the display if battery is empty. Pressure overload is hown by a red LED in the left margin of the LC-display.  The pressure gauge Type HMG6 differs from HMG1 by the additional fine djustment of the zero point on the front. By electronic correction of the linearity error of the cell it reachs a higher precision as HMG1.
